'At long last, historians now have a substantive guide to the history and work of the Consultative Group for International Agricultural Research (CGIAR). It is impossible to make sense of contemporary agriculture without understanding this organization, an essential node in post-war crop research in the Global South especially, but very little is known of its gigantic reach, its commitments, and its vision. Thanks to Curry and Lorek, this gangly institution comes into view.' Deborah Fitzgerald, MIT
